On-chip mid infrared mid-IR optical sources are a vital building blocks for many fully integrated photonic systems forsensing, imaging, communications, and signal processing applications. Passive, active and nonlinear mid-IR devices have been explored recently in several research efforts 2. Lasers have been developed in visible region 380 to 750nm and near infrared region 750 to 1800 nm. Light generation in mid-IR 2 to 20 um has been a less explored territory in integrated photonics. A unified mid-IR photonic system can enable new capabilities in sensing, signal processing and communication by reducing coupling losses, chip size, energy requirements and manufacturing cost. Chalcogenide glass ChG light sources doped with rare earth metals have been simulated in previous work 1 to be feasible for laser emission in mid-IR spectra. Demonstrated rare earth ChG bulk and fiber lasers exist in research and industry respectively. This aim of this project is to work towards a rare earth doped ChG laser on a chip.
